My invention relates toimprovements in or relating to apparatus for thespraying'of.

liquids.

H eretofore these apparatus generally comprised an indiarubber bulbwhich has a very short life by reason of the rubber being rap-` idlydeteriorated through its contact with air or with perfumed alcohol.Other known apparatuscomprise the use'of apressure piston, alreciprocating piotion'thereof acting either directly upon the liquid tobesprayedor upon the air in-'the container. Lastly,

there exists also a typeof apparatus-based upon the use of a stronginner gaseous pressure acting permanently upon the liquid'.

The present improvements relate to an`ap. paratus in which" theejectionof the liquid to be sprayed is produced through theactionv of acompressed gas or ofa Iiqueedgas contained in an inner removable case. I`The ob jects of my improvements are essentially: 'm v Firstly, toprovide anapparatus 1n which the compressed gas contained in-an innercase taneously to eject the liquid' and to divide and" atomize theejected jet in order tov produce 4a dry spraying, thatis to. say leavingvno trace upon the objects upon which the-sprayV4 is directed. f

Fourthly, to provide a spraying apparatus working with compressed'gasand using removable :cases which maybe e'asilytaken out and replacedaswell as quickly interchanged j with other similar cases..

Lastly, my invention consists also in the4 detailslof construction of myimproved spraying apparatus which will be hereafter 'inore fullydescribed.

Other objects' of'my invention will appear as this description proceeds,referenceV being had to the accompanying drawings in which Fig. 1 showsYa longitudinal section of one form of execution of ,the apparatus. l'

Fig. 2 is a sectionalview taken along the ,55

plane of the line 2-2 of Fig. 1. Referring to thedrawings, the apparatuscomprises -a body 18v preferably cylindrical,

tightly -closedat both ends by covers pressing 6-0 strongly uponVpacking rings. Said body 18 lis divided into vtwo principal compartments181, 182 limited by partition walls 19, 20. In the upper compartment181-"i's'placed a case 9- having a smaller diameter than the inner G5,diameter of the body 18 andflledwith liquid carbonio acid or otherappropriate compressed or liquefied gas, said case resting on.v n

the partition wall 19.2 A cap 6 which is screwed upon the end. of thecase 9 is pro- 70 vided with an inner ring 21 having for its object tolock a plastic packing 10 upon the case.y Upon the ring 21 isplaced arubber ring having a central conical bore closed' by means of a valve 23which can descend with- 1'5 out obturating the orifice ofthe hollowneedle 11 placed underneath in the ring 21.. The valve 23 comprises a-head 231 under which va spring blade acts vwith suflicient pressure tocause the valve to contact with its seat.

In this position thehead 231'will normally engage theupper joint whichcloses the body y 18. On the other side of said joint a pushbutton25`retained by thecover allows for downward movement of-the valve when-pres- S5 Asure is exerted upon its head. The cap`6 is formed about itsperiphery with longitudinal grooves 7 which establish Huid communica#tion lbetween the space above the cap and the 'interior of the bodyVmember .18 around the 90 case 9. i

In the space formedbetween the partition walls 19, 20 each provided withan opening 191, 201 respectively,'is placed a .tubular part -26having aspout 27 provided with a small `9`5 hole'and `conveniently-fixed to thewall of body 18. Atube 28 is engaged loosely in lthe tubular part26 itpasses through the opening 201 inthe partitionwall 20 and ex# tendsthrough the compartment 18V2 to the., 190v l of iinewire gauze forinstance.

The apparatus is actuated by simply pressing on the push button 25. Thispressure causes the opening of the valve and thus allows the passage ofthe gas which expands down between the cap 6 and container 21 intochamber 18", then through opening 19 and partition 19, whereupon itreaches the tubu-` (lar part 26, then passes through opening 20 inpartition 20 into the container 182, wherein it acts upon the liquid andcauses it to rise in the tube 28. As it escapes from the latter theliquid is atomized by the gas around the tube 28 which passes throughthe tubular part 26. The spray may be sent in all directions under thehorizontal plane. The release of the push-button will cause theimmediate interruption of the spraying.

It will be obvious that in the. apparatus described the takingfout andthe replacing of the case may be eiiected very rapidly and that theiilling-in of the liquid can be effected without any dimculty.

It will also be apparent that the compressed gas coming from the case 9does not act unon the liquid in the container before having beenvconsiderably expanded and during the whole operation all excessof-pressure is avoided in the .containen It is also to be noted that thetaking oli of compressed gas from the case takes place only during thespraying and that theV gas thus taken oit is completely utilized for thespraying so that when the apparatus is not in use the inner receptacleis not under pressure Lastly it will be seen that the spraying ofthe jetensures an atomizing jet coming out of the apparatus While l havedescribed the details of construction of preferred embodiment of myinliquid containing compartment, a compressed gas case 1n the gascontainer compartment providing a clearance space between the case andthe inner wall of said compartment, a cap at the end of said gas case inproximity to the end of the body member, said cap having a hollowperforating needle and a check valve controlling the escape of gasthrough said hollow perforating needle to the body member, a.

second cap provided with an imperforate elastic sealing member closingthe end of the body member, means operable from the exterior of thesecond cap through the elastic sealing member for unseating thecheckvalve to permit gas from the case to enter the body member, adischarge nozzle in the body member in open communication with theliquid containing compartment through an opening in the partition and atube extending' from the discharge nozzle through the opening in thepartition to near the bottom of the liquid con taining compartment.

In witness whereof, I have hereunto signed my name. f
